KT I have version 5.0.1 jailbreaked (kt-jailbreak-503) and installed KindleLouncher-1.0.1, usbnet-1.1. After the software update from version 5.0.1 to 5.0.3 I get a problem when opening of mobi format in ladnscape mode. The page is shifted to the left and the last syllable from the end of the sentence does not read. Fortunately I had kept /opt/amazon/ebook/lib directory from version 5.0.1 and I replaced MobiReader-impl.jar and everything works well.
